| Summary: | 碩士 === 國立體育大學 === 運動科學研究所 === 104 === Purpose: In this study, we designed a power exercise training (PET) program with a mouse model based on a strength and conditional training protocol for humans. We tested the effect of supplementation with functional branched-chain amino acid (BCAA)-rich sake protein (SP) to determine whether the supplement had a synergistic effect during PET and enhanced athletic performance and resistance to fatigue and Product Positioning Research. Methods: Male ICR mice were divided into 3 groups (n = 8 per group) for 4-week treatment: vehicle , PET and PET groups with SP supplementation (PET+SP). Exercise performance was evaluated by forelimb grip strength and exhaustive swimming time as well as changes in body composition and anti-fatigue activity levels of serum lactate, ammonia, glucose, and creatine kinase (CK) after a 15-min swimming exercise. The biochemical parameters were measured at the end of the experiment. Results: 4-week PET significantly increased grip strength and exhaustive swimming time and decreased epididymal fat pad (EFP) weight and area. PET+SP supplementation significantly decreased serum lactate, ammonia and CK levels after 15-min swimming exercise. The resting serum levels of AST, ALT, CREA and UA were all significantly decreased with PET+SP. Conclusion: The PET program could increase the exercise performance and modulate the body composition of mice. PET with SP conferred better anti-fatigue activity, improved biochemical profiles, and may be an effective ergogenic aid in strength training. For the product positioning of SP, we suggest that this product could be a potential ergogenic aid and accepted by young athletes by the cost and value compared to the commercial product-whey protein.
